These 15 celebs are just a few who have shed some serious weight over the years, but their stories are inspiring AF and can offer up some extra motivation when you're feeling ugh about the whole dieting thing.

Jennifer Hudson

Jennifer Hudson dropped from a size 16 to a size 6 in 2010 after teaming up with Weight Watchers, and she’s kept the 80 pounds off since. "I don't really have time to do much [working out], so I really just watch what I eat," the singer/actress told Good Housekeeping last year. "I'm very careful and cautious of what I'm eating, so I just try to pace those meals throughout the day. I'm very conscious of what I put in my body."

Kelly Osbourne

Since she made her TV debut on her family’s reality show, Kelly Osbourne has lost 70 pounds. And participating in Dancing With the Stars in 2009 is where she learned some of her healthiest habits. "[My partner, Louis van Amstel] made me eat turkey burgers and salads and explained to me that a high-protein, low-carb diet would keep me energized," she toldShape magazine at the time. "Then I started losing weight and realized, 'Oh, it’s true what they say: Diet and exercise really work!'"

Melissa Joan Hart

In 2014, Melissa Joan Hart opened up about shedding 75 pounds after giving birth, telling People she was initially inspired by her sister-in-law’s weight loss: "Sally taught me that you want to feel good about yourself. When she first started losing weight, she got compliments and they drive you to want to do more." But it's the social element of fitness that keeps her motivated to work out. "I chitchat with friends on walks or run with my husband," she told Us Magazine.

Kirstie Alley

Kirstie Alley first made headlines for her weight loss back in 2006 when she dropped 75 pounds in three years as a spokeswoman for Jenny Craig. She’s gained and lost weight since, but she still maintains a 50-pound weight loss using the program. "I’m on maintenance, so I have one Jenny Craig meal a day and then I’m on my own, but I also have my Jenny Craig consultant," she toldPeople last year. "So if I feel like I’m going awry, I just call her and she gives me some tips and a pep talk."

Adele

Adele hasn’t shared a number when it comes to how much weight she’s lost, but her figure is noticeably slimmer from when she first topped charts—even after giving birth. But it was never about the scale for her. She decided "to get in shape for myself, but not to be a size zero or anything like that" in 2015, according to Rolling Stone, and cut back on sugar (but not carbs—"I’d never deprive myself like that!" she said) to build stamina for touring.

Christina Aguilera

Christina Aguilera shed nearly 50 pounds back in 2013. She took time off from The Voice to do it—"it’s amazing what having some personal time can do, not only for the body but also for the mind and the spirit," a source toldPeople. "She has been trying new types of foods and exploring new methods of exercise. Not for diet or weight, but more for her mind and well being and overall sense of good health." Aguilera also credits reiki, an ancient Asian practice that’s said to heal your body and mind, for her weight loss.

Khloe Kardashian

Earlier this year, in a promo for her weight-loss show Revenge Body, Khloe Kardashian admitted that her family actually asked her to lose weight. She’s also documented her weight-loss journey on Instagram—in one before-and-after photo, she referenced her 40-pound weight loss, which she toldWomen’s Health was motivated by her break-up with ex-husband Lamar Odom. "If you were to ask me five years ago if ... I would be an inspiration to many others, that I would be the push that others needed to find their way. I would’ve laughed in your face. Me? The chubby one? No way!" she wrote on Instagram.

Lena Dunham

Last year, at an event for trainer Tracy Anderson, Lena Dunham debuted a much slimmer figure than she’d shown off on GIRLS. But it wasn’t about weight loss for Dunham, Anderson toldPeople. "She had significant health issues [OCD and endometriosis]," Anderson said. "She was open and transparent about her health issues, but our convoluted f-ed up celebrity culture was like, 'What diet is Lena doing? Lena lost weight,' and Lena was like, 'I was freaking sick!' She didn’t come to me to make her body look different, she came to me to feel better."

Roseanne Barr

Roseanne Barr—whose Roseanne returned to TV this year—has long been outspoken about her weight. She had a gastric bypass in 1998 ("I had my entire digestive system removed, so I should look thinner," she said per People), which helped her lose 80 pounds. And she lost even more weight in 2014—"I'm just doing the things you're supposed to do…you know, moving more, and eating less,” she toldUs Magazine.

Janet Jackson

After giving birth at 50 years old last year, Janet Jackson lost 70 pounds working with trainer Paulette Sybliss. "I started training her about six weeks after she had Eissa. We had a very vigorous training schedule," Sybliss toldE! News. "We were training a minimum of four times a week and the sessions were never less than 45 minutes, no more than an hour.” And Jackson follows Sybliss’s rule that if she’s eating well 90 to 95 percent of the time, she can eat anything that she wants in moderation. "I don't set her a cheat day at all," she explained. "If Janet feels that she needs to have a chocolate cake, [she can] go ahead and have a chocolate cake."

America Ferrera has slimmed down since her Sisterhood of the Traveling Pants days, but she’s focused more on body positivity than jean size. "How much time have I wasted on diets and what I look like? Take your time and your talent and figure out what you have to contribute to this world," the now-pregnant star toldCosmopolitan for Latinas in 2012, "and get over what the hell your butt looks like in those jeans!"

Miranda Lambert

Country singer Miranda Lambert lost about 20 pounds back in 2014 and has kept it off since—without any miracle diet. "You get tired of any diet. I've tried everything," she toldWomen’s Health. "I just literally would make grilled chicken breast, sweet potato salad. There was no miracle." For the country singer, it wasn’t about the scale, but how she felt as she approached 30. "I just thought, maybe if I get ahead of it a little, I won't have to work so hard later in life," she said to People.

Melissa McCarthy

Back in 2011, Melissa McCarthy toldPeople her body was a "work in progress," but since then, she’s lost a reported 75 pounds. She’s now a size 14, and attributes her weight loss to her laid-back lifestyle. "No trick, nothing to tell, just super boring life. You bring it real down, you don’t do anything fun and you go to bed at 7:30 — that's the trick," she toldExtra.

Jordin Sparks

American Idol alum Jordin Sparks lost 50 pounds in 18 months back in 2012, according to E! News. "I just wanted to be healthy," she toldShape at the time. "I remember thinking, 'I'm in my prime. I should be happy and fit.'" Sparks started walking every day and watching her portion sizes, then worked with a trainer to build muscle. "There's no quick or magical way to lose weight," she toldRedbook. "You just have to do it the natural way—diet and exercise and stick to it—and be able to do it at your own pace."
